Description

The base of the matrix for glass bending is related to technological equipment in the manufacture of molded glass, and more specifically for the installation and fastening of matrices for glass bending.

A known matrix for bending used at LLC Rida Glass Armored Glass Plant in the form of cast iron combining a base and a matrix for bending glass units, followed by surface treatment on a special two-rack boring milling machine (see photo 1).

The disadvantage of this technical solution is the impossibility of using this design for matrices of various sizes, the high complexity in manufacturing and metal consumption, the need to manufacture the matrix on the side.

The closest technical solution is the collapsible form for double-glazed window molding used at Rida Glass Armored Glass Plant LLC (see photo 2.).

This form consists of a removable matrix and a base in the form of a welded frame.

This technical solution provides for multiple use of the base for matrices of different sizes (see figure 1).

However, the base structure, welded from transverse and longitudinal strips, is laborious to manufacture, requires special welding conductors and additional alignment of the attachment planes after welding.

The purpose of this technical solution is to create a base design that reduces the complexity of manufacturing and the possibility of multiple use for installation and fastening of various types of matrices.

This goal is achieved by the fact that the frame is prefabricated, for which the longitudinal strips are made with vertical slots from the bottom up to a length equal to half the width of the longitudinal strips with a groove width equal to the thickness of the frame + 0.2 ÷ 0.4 mm, and in the frames the slots are made from top to bottom according to the number of longitudinal strips with a width equal to the thickness of the longitudinal bar + 0.2 ÷ 0.4 mm and a depth equal to half the width of the longitudinal bar, and the height of the frames is 10 ÷ 15 mm greater than the width of the longitudinal bars, while the lateral edges of the frames are made from the element and fastening the pulling planks in the form of grooves with a width equal to the thickness of the pulling plank with a transition to a narrowing of 1.5 ÷ 2 mm, and the grooves are located above the end of the vertical slots of the frames, and the number of longitudinal planks and frames is determined by the frame stiffness requirements depending on the size of the matrix for bending, same

end frames are made with fastening elements of the laths passing into the handles for transferring the base.

The base of the matrix 1 for bending the glass packet consists of longitudinal strips 2, frames 3, end frames 4, tightening bars 5, handles for carrying the base 6 and side longitudinal bars 15 (see FIGS. 2-6).

Longitudinal slats 2 are made with grooves 7 according to the number of frames 3 and end frames 4, half the width of the strap 2 and the width equal to the thickness of the frame + 0.2 ÷ 0.4 mm. In addition, holes 8 and 10 are made on the strips 2 and 15 for fastening the tightening strips 5 and fastening the handles 6 (see Fig. 6).

The frames 3 are made with grooves 9 according to the number of longitudinal strips 2 and 15, while the depth of the groove 9 is equal to half the width of the longitudinal bar and has a width equal to the thickness of the bar + 0.2 ÷ 0.4 mm (see Fig.6).

The end frames 4 in the lower part are equipped with thrust bearings 11 forming supporting planes, the height of the frames 3 and 4 is 10 ÷ 15 mm higher than the height of the longitudinal bars 2, for air to escape when the glass is sinking during bending, and the internal fastening of the handles 6 are located on the longitudinal bars 2 ( see Fig.6).

The tension bars 5 have bushings 12 fixed thereon (see FIG. 6). On the lateral edges of the frames 3 and 4, horizontal grooves 13 are made in width equal to the thickness of the pulling bars 5 with a transition to a narrowing of 1.5 ÷ 2 mm (see Fig. 7). On the lateral longitudinal strips 15 are mirrored after assembly of the lodgement of the mounting matrix 16 (see Fig.6).

Assembling the base as follows:

On the inverted planks 2, 15, the frames 3 are installed in the grooves 7, then the end frames 4 are installed in the same way with the thrust bearings 11 forming the supporting plane upward, the tension bars 5 are installed and fastened with bolts 17, through the holes 8, to the longitudinal bars

15, then install the handles 6 and fasten with bolts 14, through the holes 10.

By reinstalling individually or in pairs the end frames 4, you can change the coordinates of the attachment of matrices of any size, i.e. use the base repeatedly.

This design of the base of the matrix can significantly reduce the complexity of manufacturing, metal consumption and use it for a matrix of different sizes.
